More and more lip seal users at the plant maintenance level (and above) have learned that there are misconceptions and that contact seals are not the only option when it comes to protecting bearings. Seventy years ago, when lip seals were introduced, they were the only kind of bearing protection device available. Convenient and inexpensive, they went on to capture a 99% market share

ROCK ISLAND, IL, May 15, 2006 –Following on the heels of their record 2005 sales year, Inpro/Seal Company reports record results for the first quarter of 2006. The Rock Island designer, manufacturer (and inventor) of bearing isolators also reports that advance orders, shipments and projections are far ahead of projections and expectations. A milestone event also occurred during this quarter when they delivered their 2,000,000th bearing isolator.


(PRWEB) May 19, 2006 -- Though a number of issues come into play, the firm attributes much of this extraordinary success to: increased brand preference and awareness that drove them to an installed base of over two million isolators; a dynamic R & D program that fuels product expansion; talented people; the largest engineering data base of its kind; and a marketing approach backed by people and research dedicated to help the end user make an educated and informed decision.

Product Enhancements From A Very Active R & D Program

Inpro/Seal continues to invest heavily in R & D. Working out of what may be the world’s largest campus devoted specifically to bearing isolation technology, their dynamic R & D program helps fuel their growth. Backed by a laboratory that operates 24/7 with extensive field testing and trials, Inpro/Seal continues to develop new products and enhance existing products that offer measurable bottom line results. To illustrate how active their R & D is, these are a few examples:

  • MGS Motor Grounding Seal – that this emerging technology stops the damaging effects of residual shaft currents on AC motors. Its design prevents pitting, fluting and fusion craters by permanently protecting the motor bearings before damage can take place.
  • Articulating Air Mizer™- PS™ - introduced as part of the Air Mizer™series, this shaft seal provides a positive seal and prevents shaft misalignment in applications were dry particulates, powders and bulk solids are handled, processed, packaged and stored.
  • OM 32 Oil Mist Bearing Isolator – when oil mist was first put into use, stray mist and venting were not a problem. When environmental needs changed dramatically, Inpro/Seal took a tried and proven product and enhanced it to meet these needs. Today, The OM 32 is the only known method to solve housekeeping issues and permanently keep stray mist from entering the environment.
  • VBXX-MT™ Series Bearing Isolators – developed to safeguard machine tool spindles, this product provides protection coolant, chips, humidity and heat, that can cause malfunction and expensive, unscheduled downtime. The highest performance is assured with a reverse interface that avoids direct impingement of coolant and chips.
  • And More –the only product that protects rolling element bearings on paper machines from the wet end to the dry end; IEEE-841 motors that use bearing isolators as part of their specification and set the standard for bearing protection; ad hoc designs for gear boxes, axial shaft movement and one of a kind projects.

Educate And Inform Marketing Approach

According to David C. Orlowski, President and founder of Inpro/Seal Company and considered by many as the “father” of bearing isolation technology, “Over the last couple of years, we had extensive research conducted into the use of bearing protection on a market-by-market, application by application basis. The results of this research taught us that people wanted to know more about bearing isolators. From this, we adopted an educate and inform marketing approach. Our objective is to teach plant people about the features, advantages and benefits of bearing protection. To show how successful this approach continues to be, in 2005, we published a brochure entitled Introduction To Bearing Isolators…… A Short Lesson In Bearing Isolation. Now in it’s third printing, it has become the most successful literature we have ever released.

Lip Seal Users Fast Becoming Converts To Bearing Isolators

Orlowski continued, “More and more lip seal users at the plant maintenance level (and above) have learned that there are misconceptions and that contact seals are not the only option when it comes to protecting bearings. Seventy years ago, when lip seals were introduced, they were the only kind of bearing protection device available. Convenient and inexpensive, they went on to capture a 99% market share”.

Today, lip seal manufacturers state that at best, they have an average life cycle of 1,844 hours or 77 days of operation, though some may survive up to 3,000 hours. Simply put, with a 100% failure rate, in the real world, lip seals are not meant for heavy duty, industrial applications where rotating equipment is designed by their OEM’s to run, uninterrupted for five years. Another in-demand brochure, Are Lip Seals Obsolete?, provides more in-depth information. Once end users find out that bearing isolators never wear out and provide levels of protection unavailable in any kind of bearing protection device with bottom line implications, they get fed up with this 70 year old technology and quickly become a convert.

Energy Aspects

Addressing the importance of energy Orlowski said, “When engaged with a rotating shaft, bearing isolators work without contact and thus do not consume energy. On the other hand, each contact seal (lip, face) will consume, on average, 147 watts of power while operating. Each year some 400,000 bearing isolators are installed as contact seal replacements. Once you do the math, you will see that the savings is close to 600,000,000 watts. Or take a plant with 600 operating pumps that can save $117,000 just by replacing contacting with non-contacting technology. Add to that the costs associated with downtime and you can again see why more and more end users are switching to Inpro/Seal bearing isolators.”

VBXX-D, The Next Generation

When Inpro/Seal introduced their original VBX™ series fifteen years ago, it provided end users with a way to eliminate the root cause of premature equipment failure – contamination entering the bearing environment – while increasing productivity and reliability in the process. Since then, hundreds of thousands have been installed in plants around the world. Today, the VBXX-D the next generation in bearing isolators has taken hold offering the latest and best non-contacting labyrinth sealing technology to improve plant uptime and reliability with an ROI that more than doubles previous results with levels of bearing protection previously unavailable.

Industry Leading Internet Support

Inpro/Seal has also invested heavily into web sites dedicated to the education of bearing isolation technology with much downloadable information. When an end user visits or they will find a wealth of information related to both Inpro/Seal and bearing protection, including: specific applications, case histories, data sheets, facts and questions, specifications and more. Interactive spreadsheets include a Cost Justification Worksheet and Contact Seal Energy Consumption Calculator. Simply to complete, an end user merely fills in the blank to calculate ROI and benchmark repair costs.

People Make A Difference

Orlowski concluded by stating, “The cumulative efforts of our employees, including management, staff and distributors are key to providing world class support and helps fuel our growth strategies. These talented people are specially trained in tribological and lubrication techniques and have the necessary process know how. Our guideline to promote from within helps us cultivate and retain these resources and allows our customers to deal with people that know our company, our products and the way our products are applied.
